No one can rightly accuse me of being a Volvo fan, Mercedes and BMW fan yes. Nonetheless, I want to give Volvo what credit I think it is due. Nivomats, I think, are effective at keeping level Volvo sedans and wagons that carry passenger or cargo weight in the rear, and not expensive at around $200 each street price. Consider they last a long time and the lifetime warranty from Boge and Nivomats look like a bargain to me. Consider that warranty and Brickboarders that keep their Volvos nearly forever, and Nivomats look to me like an all time bargain in top notch passenger car or wagon rear suspension. If you want a sports sedan, then you may want to put in 740 rear springs with Bilstein shocks on a 760. Still, it will not be a BMW 5 series. Best regards.
